. My-invention relates to an improvement in indows, wherein it isdesired to provide a more o'jtive window structure.

:With most conventional types of double sash in'dows now in use, it iscommon practice to emy a window screen in the window frame. durin warmweather and in cold climates to replace th s .screen with a storm windowduring: cold weather. This necessitates changing screens and stormwindows twice each year and provides "eifective insulation when it isdesired to prevent at from entering thehouse. Somepersons .1 illowthepractice of completely closingtheir house during the hottest hours ofthe day. Open- ;t hewindows to cool thehouse during thecool hgurs;requires the presence of a screen in the window in most territories.Therefore in the {warmer hours a single double sash window insulatesthewarm air outdoors from thecooler air inside the building. I V s lt isthe object of the present invention to proaide a window having two setsof double hung window sashes therein and having a screen -in-. terposedbetween one window sash and the op'-' jposite end of the frame. Theouterinostwinnews act in the capacity'of 'storrn' windows, thusi'e'tviating the nece'ssityof adding storm windows .l'cold'fw'eather.,At the same time, however,

. 156th of the windows may be-close'd' at any time of theyear toprovideaneifective insulation in hot -1 arena weather. The window may likewisebe 0 e'ned'in the usual mannenand the opening 'ec'ted by a screen.

A feature of the present invention lies'inthe ovision'o'fa wide flushstill extending inwardly oni'thej inner window in the usual manner, and

extending outwardly 'into' proximity with the outer window. A wide fiatshelf'or table is thus formed when"the"l ower'sash of the inner win-(low israised': added advantage of the sill 40 ddji struction lies in"the fact that the sill itself as be removed rrotn'the outside of thewindow A further feature of thepresent-invention lies i'n jthe fact thatthe screen may be opened if a desired to permit'the-window opening to beunobstructed; When bothfof the lowei 'wiridow sashes are in raisedposition; a'per'son inside the-window has access to'the window screen.The-screen may.

then be swung outwardly and entirely removed if necessary. r H

feature of thepresent invention resides in the provision of a'windowlocking apparatus which prevents thewindowfrom being opened from theoutside. "Thislockingapparatus is operatedau'to-v.

matically upon the lowering of the lower portion of the inner windowsash, thus obviating the necessity of locking the window. 7 n

.Afurtherfeature of the present invention lies in the fact that thewindow sill is provided with a movable member which may be moved intoen-, gagement with the outer window sash. This movable member isactuated by the closing of the lower sash .of the inner window, thuspreventing a draftthrough the window due to a crack or space betweenjthewindow sash and the sill.

A further feature Ofwthe present invention resides-in-the fact that thesash may, if desired, contain a plurality of panes of transparentmaterial, thus increasing the insulating eiTect. If it is-so desired, ashee-t-of somewhat flexible glass or plastic maybe inserted in a grooveextending about the awi'ndow pane opening of each sash, thus providingadouble window effect. In such a construction, the frame is providedwith a fixed integral shoulder-externally of the window pane in whichthe'groove for the extra pane is provided. Theseand other objects andnoveljeatures of myinventionflwill be more clearly and fully set forthin the following specification and claims. I in the drawings forming apart of my specificationz', f" 1 1 Figure; 1- is a perspective view of awindow frame-embodying the construction of my invention: Q

The groove I'l' extends only a portion of theentireheight of the window, allowing-the window to open for ventilationpurposes; but'providing an opening too small for a person to climbthrough,

A guide for vertical sliding movement of the lower sash 20 of the outerwindow is provided by the parting stop I9 and the parting stop 2 I. Theupper sash 22 of the outer window is held in place by a right angularguide strip 23 which extends across the top of the frame beneath thelevel of the head jamb II and extends to the bottom of the upper sash 22in raised position of this sash.

By removing the window stops and parting stops 54, i and H arid heguide'stifi'pfflfthesill may be removed from the exterior o'f'the'window for repair or replacement. The sill I3 is slidably supportedbetween the side jambs l2 and between the inner sill stop and the bottomplateylB-isecured to the lower ends of the side lambs I2.
